Busy sleep :-) < I thought busy waiting was frowned upon>
Actually after 10 works as well.
So a work-around is to set the timer 10 ms *before* I want and run a busy sleep
loop -
So I keep having to thumping the damn thing to make it doesn't fall asleep.
I've only tested on an unloaded system - perhaps if the system was loaded
the timings would be better?
Thanks for the tip.
